By using the cooperation of the top connection frame 10, the three downward-probing support claw arms 20, the three bottom wheel assemblies 30, the mattress storage assembly 200, and the top rotation mechanism 300 for operation, the problems of inconvenient transportation and poor transportation flexibility of large mattresses are solved.

[0036] Working principle:

[0037] The first step: One of the three downward-probing support claw arms 20 is in the direction where the mattress is placed. The three downward-probing support claw arms 20 only occupy half of the spherical space. Align the mattress placement direction.

[0038] The second step: Adjust the positions of the locking screw 80, the vertical through holes 631, and the threaded holes 531 to make the placement gap 90 appropriate.

[0039] The third step: Place the mattress into the mattress storage assembly 200 and adjust the top rotation mechanism 300 to an appropriate position.

[0040] Step 4: Start to move or transport the mattress. After reaching the designated position, unload it.

[0041] In the first aspect of the present invention, as a preferred embodiment, the downward-probing support claw arm 20 is composed of a plurality of rectangular mounting frames 201, and adjacent rectangular mounting frames 201 are connected in a detachable and fixed manner. The purpose of using the "rectangular mounting frame 201" is that large-sized mattress auxiliary transportation devices with different specifications and sizes can be designed specifically, and the applicability is strong.

[0042] In the first aspect of the present invention, as a preferred embodiment, the downward-probing support claw arm 20 includes a top connecting arm 21, a middle connecting arm 22, and a lower vertical connecting arm 23. The two ends of the middle connecting arm 22 are respectively connected to the top connecting arm 21 and the lower vertical connecting arm 23. The angle between the extending direction of the top connecting arm 21 and the extending direction of the lower vertical connecting arm 23 is A1 and is an obtuse angle, and the angle between the extending direction of the top connecting arm 21 and the extending direction of the middle connecting arm 22 is A2 and is an obtuse angle. Specifically, A2 > A1, and A2 is between 150° and 170°. The purpose of setting the "lower vertical connecting arm 23" is to improve the overall stability.

[0043] It should be particularly noted that "the 3 downward-probing support claw arms 20 only occupy half of the spherical space, and align the direction of placing the mattress" is one of the key points to solve the problem. At the same time, the 3 downward-probing support claw arms 20 form stable support points. On the one hand, it is convenient to put the mattress in and take it out, and on the other hand, the stability is good. The downward-probing support claw arm 20 includes a first inclined section, a second inclined section, and a third inclined section composed of rectangular mounting frames 201. The second inclined section is connected to the ends of the first inclined section and the third inclined section by means of hinge or fixation.

[0044] In the first aspect of the present invention, as a preferred embodiment, the bottom wheel assembly 30 includes an upper connecting disk 31, a side bracket 32, and a roller assembly 33. The upper connecting disk 31 is fixed on the side bracket 32, and the roller assembly 33 is rotatably installed on the side bracket 32. An auxiliary placement column 34 is provided along the inner side of the upper connecting disk 31, and the auxiliary placement column 34 is provided with an upper arc-shaped end face 341, which is convenient for placing the mattress into the mattress storage assembly 200.

[0045] In the first aspect of the present invention, as a preferred embodiment, the latch screw 80 includes a gripping portion 81 and a threaded portion 82, and the gripping portion 81 is connected to the threaded portion 82. The gripping portion 81 includes a top cover 811, a middle connecting column 812, and a lower connecting portion 813. The upper and lower ends of the middle connecting column 812 are respectively connected to the top cover 811 and the lower connecting portion 813. The mattress storage assembly 200 further includes a middle tension spring 70. The two ends of the middle tension spring 70 are respectively connected to the first receiving member 50 and the second receiving member 60, and the middle tension spring 70 is located in the upper middle part of the first receiving member 50. The whole device has a compact structure and is easy to operate.

[0046] The above embodiments are only the preferred embodiments of the present invention, and cannot be used to limit the scope of protection of the present invention. Any non-substantive changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
